The Titanic was built at the Harland and Wolff shipyard in Belfast, and designed to compete with the rival Cunard Line's Lusitania and Mauretania. The Titanic, along with her Olympic-class sisters, the Olympic and the Britannic (called Gigantic at first), were intended to be the largest, most luxurious ships ever to operate. The designers were Lord Pirrie, a director of both Harland and Wolff and White Star, naval architect Thomas Andrews, Harland and Wolff's construction manager and head of their design department, and Alexander Carlisle, the shipyard's chief draughtsman and general manager.
Construction of RMS Titanic, funded by the American J.P. Morgan and his International Mercantile Marine Co., began on 31 March, 1909. Titanic's hull was launched on 31 May 1911, and her outfitting was completed by 31 March the following year. Her length overall was 269.1 m, the moulded breadth 28.0 m, the tonnage 46,328 GRT, and the height from the water line to the boat deck of 18 m. She was equipped with two reciprocating four-cylinder, triple-expansion steam engines and one low-pressure Parsons turbine, which combined drove three propellers. There were 29 boilers fired by 159 coal burning furnaces that made possible a top speed of 23 knots. Only three of the four 19 m funnels were functional: the fourth, which served only for ventilation purposes, was added to make the ship look more impressive. The ship could carry a total of 3,547 passengers and crew.
The Titanic closely resembled her older sister Olympic. Although she enclosed more space and therefore had a larger gross register tonnage, the hull was almost the same length as the Olympic's. Two of the most noticeable differences were that half of the Titanics's forward promenade A Deck was enclosed against outside weather, and her B Deck configuration was different from the Olympic's. As built the Olympic did not have an equivalent of the Titanic's Café Parisien: the feature was not added until 1913. Some of the flaws found on the Olympic, such as the creaking of the aft expansion joint, were corrected on the Titanic. The skid lights that provided natural illumination on A deck were round, while on Olympic they were oval. The Titanic's wheelhouse was made narrower and longer than the Olympic's. These, and other modifications, made the Titanic 1,004 gross register tons larger than the Olympic.
The vessel began her maiden voyage from Southampton, England, bound for New York City, New York on 10 April 1912, with Captain Edward J. Smith in command. On the maiden voyage of the Titanic some of the most prominent people of the day were travelling in first-class. Among them were millionaire John Jacob Astor IV and his wife Madeleine Force Astor, industrialist Benjamin Guggenheim, Macy's owner Isidor Straus and his wife Ida, Denver millionairess Margaret "Molly" Brown (known as 'Unsinkable Molly Brown'), Sir Cosmo Duff Gordon and his wife couturière Lucy (Lady Duff-Gordon), George Elkins Widener and his wife Eleanor; cricketer and businessman John Borland Thayer with his wife Marian and their seventeen-year-old son Jack, journalist William Thomas Stead, the Countess of Rothes, United States presidential aide Archibald Butt, author and socialite Helen Churchill Candee, author Jacques Futrelle his wife May and their friends, Broadway producers Henry and Rene Harris and silent film actress Dorothy Gibson among others.
Titanic surpassed all her rivals in luxury and opulence. The First-class section had an on-board swimming pool, a gymnasium, a squash court, Turkish bath and a Verandah Cafe. First-class common rooms were adorned with ornate wood panelling, expensive furniture and other decorations. In addition, the Café Parisien offered cuisine for the first-class passengers, with a sunlit veranda fitted with trellis decorations. There were libraries and barber shops in both the first and second-class. The third class general room had pine panelling and sturdy teak furniture. The ship incorporated technologically advanced features for the period. She had three electric elevators in first class and one in second class. She had also an extensive electrical subsystem with steam-powered generators and ship-wide wiring feeding electric lights and two Marconi radios, including a powerful 1,500-watt set manned by two operators working in shifts, allowing constant contact and the transmission of many passenger messages. First-class passengers paid a hefty fee for such amenities. The most expensive oneway transatlantic passager.
On the night of Sunday, 14 April 1912, the temperature had dropped to near freezing and the ocean was calm. The moon was not visible and the sky was clear. Captain Smith, in response to iceberg warnings received via wireless over the preceding few days, had drawn up a new course which took the ship slightly further southward. That Sunday at 13:45, a message from the steamer Amerika warned that large icebergs lay in the Titanic's path, but as Jack Phillips and Harold Bride, the Marconi wireless radio operators, were employed by Marconi and paid to relay messages to and from the passengers, they were not focused on relaying Ice messages. Later that evening, another report of numerous large icebergs, this time from the Mesaba, also failed to reach the bridge.
At 23:40, while sailing about 400 miles south of the Grand Banks of Newfoundland, lookouts Fredrick Fleet and Reginald Lee spotted a large iceberg directly ahead of the ship. Fleet sounded the ship's bell three times and telephoned to the bridge. First Officer Murdoch gave the order "hard-a-starboard", using the traditional tiller order for an abrupt turn to port (left), and adjusted the engines. The iceberg brushed the ship's starboard side (right side), buckling the hull in several places and popping out rivets below the waterline over a length of 90 m. As seawater filled the forward compartments, the watertight doors shut. However, while the ship could stay afloat with four flooded compartments, five were filling with water. The five water-filled compartments weighed down the ship so that the tops of the forward watertight bulkheads fell below the ship's waterline, allowing water to pour into additional compartments. Captain Smith, alerted by the jolt of the impact, arrived on the bridge and ordered a full stop. Shortly after midnight on 15 April, following an inspection by the ship's officers and Thomas Andrews, the lifeboats were ordered to be readied and a distress call was sent out.
Jack Phillips and Harold Bride were busy sending out CQD, the international distress signal. Several ships responded, including Mount Temple, Frankfurt and Titanic's sister ship, Olympic, but none was close enough to make it in time. The closest ship to respond was Cunard Line's Carpathia 93 km away, which could arrive in an estimated four hours
From the bridge, the lights of a nearby ship could be seen off the port side. The identity of this ship remains a mystery but there have been theories suggesting that it was probably either the Californian or a sealer called the Sampson. The first lifeboat launched was Lifeboat 7 on the starboard side with 28 people on board out of a capacity of 65. The Titanic carried 20 lifeboats with a total capacity of 1,178 people. While not enough to hold all of the passengers and crew, the Titanic carried more boats than was required by the British Board of Trade Regulations. At the time, the number of lifeboats required was determined by a ship's gross register tonnage, rather than her human capacity.
Around 02:10, the stern rose out of the water exposing the propellers, and by 02:17 the waterline had reached the boat deck. The last two lifeboats floated off the deck, collapsible B upside down, collapsible A half-filled with water after the supports for its canvas sides were broken in the fall from the roof of the officers quarters. Shortly afterwards, the forward funnel collapsed, crushing part of the bridge and people in the water. On deck, people were scrambling towards the stern or jumping overboard in hopes of reaching a lifeboat. The ship's stern slowly rose into the air, and everything unsecured crashed towards the water. While the stern rose, the electrical system finally failed and the lights went out. Shortly afterwards, the stress on the hull caused Titanic to break apart between the last two funnels, and the bow went completely under. The stern righted itself slightly and then rose vertically. After a few moments, at 02:20, this too sank into the ocean.
Only two of the 18 launched lifeboats rescued people after the ship sank. Lifeboat 4 was close by and picked up five people, two of whom later died. Close to an hour later, lifeboat 14 went back and rescued four people, one of whom died afterwards.
As the ship fell into the depths, the two sections behaved very differently. The streamlined bow planed off approximately 609 m below the surface and slowed somewhat, landing relatively gently. The stern plunged violently to the ocean floor, the hull being torn apart along the way from massive implosions caused by compression of the air still trapped inside. The stern smashed into the bottom at considerable speed, grinding the hull deep into the silt.
After steaming at 17.5 knots for just under four hours, the RMS Carpathia arrived in the area and at 04:10 began rescuing survivors. By 08:30 she picked up the last lifeboat with survivors and left the area at 08:50 bound for New York.
The idea of finding the wreck of Titanic, and even raising the ship from the ocean floor, had been around since shortly after the ship sank. No attempts were successful until 1 September 1985, when a joint American-French expedition, led by Jean-Louis Michel (Ifremer) and Dr. Robert Ballard (WHOI), located the wreck using the side-scan sonar from the research vessels Knorr and Le Suroit. In June 1985, the French ship Le Suroit began systematically crossing the 150-square-mile target zone with her deep-search sonar. Le Suroit covered 80 percent of the zone, leaving only 20 percent for the American ship Knorr. It was found at a depth of 4 km, slightly more than 600 km south-east of Mistaken Point, Newfoundland at 41°43′55″N 49°56′45″W / 41.73194°N 49.94583°W / 41.73194; -49.94583 Coordinates: 41°43′55″N 49°56′45″W / 41.73194°N 49.94583°W / 41.73194; -49.94583, 21 km from fourth officer Joseph Boxhall's last position reading where Titanic was originally thought to rest. Ballard noted that his crew had paid out (3,810 m of the sonar's tow cable at the time of the discovery of the wreck, giving an approximate depth of the seabed of 3,795 m. Ifremer, the French partner in the search, records a depth of 3,800 m, an almost exact equivalent. These are approximately 2.33 miles, and they are often rounded upwards to 2.5 miles or 4 km. Video cameras aboard the unmanned submersible Argo were the first to document the Titanic's visual state on the bottom of the ocean. The submersible was based on the Knorr and the images retrieved were featured in National Geographic by December 1985. In 1986, Ballard returned to the wreck site aboard the Atlantis II to conduct the first manned dives to the wreck in the submersible Alvin.
Ballard had in 1982 requested funding for the project from the US Navy, but this was provided only on the then secret condition that the first priority was to examine the wreckage of the sunken US nuclear submarines Thresher and Scorpion. Only when these had been photographed did the search for Titanic begin.
The most notable discovery the team made was that the ship had split apart, the stern section lying 600 m from the bow section and facing opposite directions. There had been conflicting witness accounts of whether the ship broke apart or not, and both the American and British inquiries found that the ship sank intact. Up until the discovery of the wreck, it was generally assumed that the ship did not break apart.
The bow section had struck the ocean floor at a position just under the forepeak, and embedded itself 18 m into the silt on the ocean floor. Although parts of the hull had buckled, the bow was mostly intact. The collision with the ocean floor forced water out of Titanic through the hull below the well deck. One of the steel covers was blown off the side of the hull. The bow is still under tension, in particular the heavily damaged and partially collapsed decks.
The stern section was in much worse condition, and appeared to have been torn apart during its descent. Unlike the bow section, which was flooded with water before it sank, it is likely that the stern section sank with a significant volume of air trapped inside it. As it sank, the external water pressure increased but the pressure of the trapped air could not follow suit due to the many air pockets in relatively sealed sections. Therefore, some areas of the stern section's hull experienced a large pressure differential between outside and inside which possibly caused an implosion. Further damage was caused by the sudden impact of hitting the seabed; with little structural integrity left, the decks collapsed as the stern hit. Approximately 6,000 artefacts have been removed from the wreck. Many of these were put on display at the National Maritime Museum in Greenwich, England, and later as part of a travelling museum exhibit.
Many scientists, including Robert Ballard, are concerned that visits by tourists in submersibles and the recovery of artefacts are hastening the decay of the wreck. Underwater microbes have been eating away at Titanic's steel since the ship sank, but because of the extra damage visitors have caused the National Oceanic and Atmospheric Administration estimates that the hull and structure of the ship may collapse to the ocean floor within the next 50 years. Surrounding the wreck is a large debris field with pieces of the ship, furniture, dinnerware and personal items scattered over one square mile (2.6 km²). Softer materials, like wood, carpet and human remains were devoured by undersea organisms.
Contrary to popular mythology, the Titanic was never described as "unsinkable", without qualification, until after she sank. There are three trade publications (one of which was probably never published) that describe the Titanic as unsinkable, prior to her sinking, but there is no evidence that the notion of the Titanic's unsinkability had entered public consciousness until after the sinking.RMS Titanic in past and now, present, is one of the most famous ships that the world known. In James Cameron movie was "the ship of dreams".
